New Ampeg B115E breaks up - asking too much?

    Just bought an Ampeg B115E 1x15 cab, driving it with a MicroVr. The B115E breakups big time - like something is about to fly apart - if I boost the bass control on the amp and turn it up to "club level" volume - which is pushing the VT head pretty hard.

    So, is the cab defective? I was expecting pure clean sound as long as I stayed within the wattage specs. But it sounds like a cheapo ******** pile of crap when driven a little bit.

    It's a new cab (but I discarded the shipping box, etc.), what would you advise? I like the size and weight of the B115E, but it's almost embarrassing how ****** this thing sounds when you get it playing volume (and I'm not talking about filling a stadium, just an average club).

    Thanks for your thoughts,

    Boosting the bass control at high volume with a small cabinet = that. Physics are against you.

    In the end it's still a single 15, so yeah it has limitations and we're also assuming the amp isn't hitting clipping, etc. There is such a huge difference between a single 15 and a pair of 15s.

    While your decision to fall withing the amp/cab wattage ratings, if you follow some of the speaker gurus on TB (Bill Fitzmaurice, Greenboy and others), you'll quickly learn that cab wattage ratings means almost nothing in regards to how it will handle loud, low notes. Only the speaker ratings (Xmax, etc) mean something and if the cab is designed for a specific speaker pretty much is the ballgame.


    Sounds like you're pushing the amp pretty good as well. Having to turn up the bass eq. may also mean that your amp is running out of headroom.

    Seems like you need a cab with a more heavy duty speaker(or two or four) and more efficiency.

    If you still can return it, find a box (maybe a local music store can help you out?) and send it back. IMO, if you do anything else, you'll be throwing good money after bad.

    An idea to consider: maybe you can borrow one or two 2x15's or a couple of 2x10's (vertically stacked) and see how it goes at your next gig.

    PS. I advise you to keep original packaging for up to a year. Never throw out packaging for new large, purchases. I store them in my garage. You never know....:bassist: I would also advise you to keep the amp/cab from distorting so you don't blow the speaker and then you can't return it. Maybe you can get some PA support for it at your next gig?

    So... I'm thinking of adding a 2x10 into the mix with this B115E. Decisions decisions...

  6. Add a second B115E or start over with 2 210's. Don't add a 210 to the 115.

    What are your knob settings on the Micro VR? What kind of bass? The B115e's a budget cab but it should be able to handle the Micro VR. Most SS amps will run pretty nasty when you run them wide open and try to go past its available wattage, though, and it's possible to pass that point with a Micro VR. Also, if you run with a lot of bass knob crankage, you divert a lot of wattage to low frequencies, and that will cause your amp to run out of clean wattage quicker. And amp distortion can sound just like speaker distortion. So we'd need your bass and knob settings on bass and amp to give you any sort of a clear answer.
  8. In other words, asking too much of a mini-micro amp and a single 15"? ;)

    Well, I have the answer folks!! I decided to remove the grill and look under the hood. Lo and behold, they installed a rear mount speaker in a front load cab! The speaker should be in a rear loaded cab, because the paper/cardboard gasket is on the front-facing side of the mounting flange. I could not believe it!!! How could they make such a mistake?! How many B115E's out there have this incorrect speaker configuration?

    I happened to have a FRONT mount 15" speaker (with the gasket on the REAR side of the mounting flange), so I uninstalled the factory - WRONG - speaker type, and installed a CORRECT front mount 15. BINGO! Everything sounded great - as I expected in the first place.

    Such an egregious error is unforgivable from a name such as AMPEG. Heads should roll. There ought to be a "recall". Check your B115E, if you have one. DO NOT BUY one if you don't.

    DISCLAIMER: I am an endorser, but I know many of the guys at Ampeg, and trust me, they're not in the business of ripping anyone off. I'm assuming you bought it new, so if you did, you should call them and email them pics. If the speaker doesn't have the right gasket for the right way to mount it, they'll send you a new one. This would certainly be a mixup at the factory rather than a vast conspiracy to sell cabs with the wrong speaker gasket. What's in it for them to do that? Saving 3 cents on rubber? Call Ampeg tomorrow.

    Again, this is assuming you bought it new. If you bought it used, it could have been a previous owner tampering with it. Don't know...wasn't there, didn't see pics...but if you bought it new, you'll get taken care of if you handle it through Ampeg and not Talkbass.

    Heads should roll? Too good for them. Nothing short of a public stoning should result from such egregiousness. But for justice to be fully served, disembowelment while alive followed by their entrails being eaten by egrets is the only way for the folks at Loud (all of them, of course) to expiate this heinous egregiousiosity

    Plus a unit of numerical measurement that is neither a fraction, equal to or less than zero, or used to indicate a plurality.

    The only speakers I've ever seen mounted in bass cabinets ALL had a gasket on the front even though they were rear mounted. The manufacturers include the front gasket so the speaker can be mounted either way. If the baffle is carpeted, usually the cabinet maker leaves out any gasket because the carpet is enough of a gasket, but they can leak if the speaker isn't screwed down properly. Maybe that's all that was wrong with the original speaker.

    It better be a good one.

    I've got an American made PR15H listed in the for sale section.

    Solid as a rock, but heavy.

    The B115E is rated for 200W ... I just sold mine a month or so ago, and it was more than adequate for my country band gigs in large halls. But ... it's NOT the cab I would want for rock/metal in a club setting.
  17. The vast majority of drivers made can be either front OR rear mounted. So what was the "correct" driver that you installed???

    @JimmyM. Yes, I've decided to take this up with Ampeg support. On further inspection of the factory speaker, there is some small and uneven thing around that back of the mounting flange that I suppose might be called a gasket, but it's too small and in too poor condition to ever have a chance or be effective. I'll send them detailed pics, etc. If they **** me, I'm done with ampeg forever. We'll see...

    @bassmanPaul: The speaker that I dropped in is a 15" from a 1975 Music Man 115RH Sixty Five cab. I've abused it for decades. BUT it has the expected paper/cardboard gasket on the correct (rear) side. To my surprise and thrill, it "fixed" my issues I was having with the original factory cab/speaker. Now it sounds great! But, I didn't pay money for a speakerless cab, I want Ampeg to make this right.

    I'll keep ya posted...

    All of them, along with just about every other bass cab ever made. All musical instrument drivers have a gasket on the front of the flange, to allow rear mounting if desired. Most can be front mounted as well, preferably with a gasket, of course.

    I wouldn't use that a standalone for a bass heavy tone on a club gig. I'd start with twice as many cabs and go from there.
